Title: Automatic aircraft flight control systems
IPC: G05D1/00
Filed: 1971-07-30
Abstract: 1340719 Automatic control of aircraft SPERRY RAND CORP 30 July 1971 [7 Aug 1970] 35924/71 Heading G3R In an automatic aircraft flight control system having an integrator, changes in the command value of a variable are supplied to the integrator from a manually operable rate generator, and the integrator is "enabled" (unclamped) by means responsive to the rate generator. As shown, pitch attitude is controlled by the output of integrator 12, which is compared at 11 with an actual pitch attitude signal and with a "displacement path command" to produce a surface servo controlling signal. The normal input to the integrator is an "integral path command" signal, but for pitch control only switches 9, 10 disconnect the input signals and the integrator is "clamped" to maintain the prevailing pitch. If this is to be changed, a thumbwheel 1 is turned to drive a generator 3 through gearing 2, the generator output being filtered at 4 and applied to the input of the integrator through a matching device 7 and summing junction 8. The correcting signal is only effective, however, when it exceeds a threshold set at 5 and a "pitch mode" signal is present on an AND gate 6 to unclamp the integrator. When the automatic system is disconnected a switch 13 is closed so that the integrator output tracks the actual pitch attitude signal so that zero correcting signal is produced, to avoid shock on switching back to automatic. In Fig. 2 (not shown) the system controls vertical speed, the actual value of which is supplied from a data computer, the speed error forming the input signal for the pitch attitude control loop of Fig.1. The generator in this case signals a change in the desired value of vertical speed, the threshold detector operating a switch (21) to switch-in the generator and to clamp the pitch integrator while the change is being effected.

Title: Method of and apparatus for the manufacture of aldehydes or ketones
IPC: B01J31/40
Filed: 1959-10-26
Abstract: Aldehydes and ketones are produced by the oxidation of an olefine with an aqueous catalyst solution containing a compound of a metal of the platinum group and a salt of copper and/or iron, the olefine being reacted under pressure with the catalyst solution by passing the olefine in succession through two reaction vessels, fresh catalyst solution being supplied separately to each reaction vessel and the catalyst solution being regenerated by oxidation with oxygen or an oxygen-containing gas.  Preferably the partially reduced catalyst solution is released from pressure in a distillation column to evaporate the carbonyl compound before the solution is regenerated.  Both the reaction stages and regeneration stage are normally carried out at 50-200 DEG C. and under a pressure of 2 to 50 atmospheres.  A description of suitable apparatus for carrying out the process is given.  An example is given of the conversion of ethylene to acetaldehyde. Specifications 876,025 and 884,962 are referred to.

Title: Pulse circuit including negative resistance diodes
IPC: H03K3/315
Filed: 1961-10-12
Abstract: 997,018. Semi-conductor monostable circuits. RADIO CORPORATION OF AMERICA. Oct. 12, 1961 [Nov. 2, 1960; Nov. 23, 1960], No. 36729/61. Heading H3T. A monostable pulse-generating circuit delivering a substantially flat-topped output pulse in response to an input triggering pulse comprises two tunnel diodes one of which is so biased through an inductor as to operate as a monostable circuit while the other is so biased through a resistor as to operate as a bi-stable circuit, the two tunnel diodes being coupled together through a tunnel rectifier or other diode which normally constitutes a high impedance between the tunnel diodes but which when one tunnel diode switches its state becomes momentarily of low impedance to cause the state of the other to switch so that the bi-stable circuit switches in synchronism with the monostable circuit and thus delivers a flat-topped output pulse in response to the application of a trigger pulse to one of the tunnel diodes. A trigger pulse 8 switches monostable tunnel diode TD1 to its highvoltage state whence it returns after a delay, the voltage at the junction of the tunnel diode and the inductor L being initially switched to a high valve and then decaying until the tunnel diode switches back to its low-voltage state. Under steady conditions tunnel rectifier TR presents a high resistance; when however tunnel diode TD1 switches to its high-voltage state the potential difference across the tunnel rectifier TR is such that its resistance becomes very low so that the high voltage is applied to bi-stable tunnel diode TD2 which accordingly switches to its high-voltage state. The tunnel rectifier now presents a high resistance once more and tunnel diode TD2 retains its high-voltage stable state until tunnel diode TD1 switches back to its low-voltage state whereupon the potential difference across the tunnel rectifier becomes such as to render it conducting and the bi-stable tunnel diode TD2 is switched back to its low voltage state. In an alternative embodiment, Fig. 5 (not shown) the triggering pulse is applied to the bi-stable tunnel diode; this in turn triggers the monostable tunnel diode which when it switches back to its original (high-voltage) state switches the bistable tunnel diode back to its original (lowvoltage) state.

The term "non-oxidizable ester forming group" is defined as a conventionally employed carboxylic acid protecting group which is unreactive with ozone under the specified reaction conditions, e.g. benzyl, benzhydryl, p-nitrobenzyl, 2,2,2-trichloroethyl, t-butyl and methyl. "Substituted phenyl" refers to a group of formula in which R 3  is C 1  to C 4  alkyl, C 1  to C 4  alkoxy, halogen, hydroxy, nitro, NH<SP>+</SP> 3  or protected amino, and m is 1 or 2. Suitable inert solvents are water, aqueous or non-aqueous acetone, methanol or ethanol, chlorinated hydrocarbons, and esters such as ethyl and isopropyl acetate. The ozone is provided as ozonized oxygen produced by a conventional electrical discharge procedure. The oxidation yields a mixture of the α- and #-sulphoxides in varying proportions; these isomers may be separated from each other by chromatography on silica gel.
